Is there really any reason to believe they would abolish industry?
I admit I don't know much about this topic, but I don't think it's easy at all to get another Khmer Rouge. Pol Pot and co were pretty unique as far as I know. They started out as pretty-standard Soviet-aligned Marxists, then switched to Maoism as they re-aligned to China, grew the ethno-nationalist component that they had had from the beggining, began hating everyone, became completely isolated, and then just went batshit crazy.
I doubt 1980s Peru has the same recipe for insanity. If Shining Path got to power, they would most likely just try to emulate Maoist China...
So, we get a very repressive regime, a sluggish economy, tons of people die, probably there's a famine, but please, hold your horses before you begin talking about the Khmer Rouge
Of course, a lot depends on how they get to power. If they have to share power with someone, I could even see them going the way of Nepalese Maoists
